A bodysuit is a one-piece form-fitting or skin-tight garment that covers the torso and the crotch. The design of a basic bodysuit is similar to a one-piece swimsuit and a leotard, though the materials may vary. Thong or T-front thong bodysuits usually have the crotch opening moved up to the front to underbelly area to increase the wearer's comfort. A bodysuit may have sleeves and varying shoulder strap and collar. Bodysuits can be made from a number of fabrics, including cotton, lace, nylon, etc. In general, textile bodysuits include expandable fiber such as spandex for a better fit to the shape of the body.
A bodysuit is normally worn with trousers or a skirt. The top, torso part may act as a top for the smooth line it gives or because it cannot become untucked from trousers or skirt. They may also be worn generally by women as underwear, activewear, or foundation garments. Unlike a leotard, a bodysuit is not usually considered a form of athletic wear.
